Reserved. Unknown During Read.
Fast done status. Read-only bit indicating that the FIR
transmit module has completed transition of the current
frame and that it is safe to disable the module using the
EN control bits.
Medium done status. Read-only bit indicating that the MIR
transmit module has completed transmission of the current
frame and that it is safe to disable the module using the
EN control bits.
Loopback Mode, for MIR and FIR operation.
0 - Normal operation.
1 - Loopback active, the transmit serial shifter is directly
connected to the receive serial shifter.
